Southwest Airlines flight cancellations picked up Monday as planes were grounded for engine inspections following a midflight engine failure last week that killed a passenger.

The airline said 40 flights were halted Sunday, characterizing the cancellations as minimal, affecting about 1 percent of nearly 4,000 scheduled flights.

On Monday, 129 flights were canceled, according to Flightaware. The airline did not confirm the number. In an emailed statement, it said that because its “operational plans entail multiple aircraft entering and exiting scheduled service” during inspections it is unable to provide “real-time, continuous updates on total flight disruptions.”

“Again, we are working directly with impacted customers on the minimal flight changes this week as we work diligently to ensure the safety of our fleet,” Southwest said.

Five Southwest flights at Bradley International Airport in Windsor Locks were delayed, but were not canceled, according to Flightaware.

Southwest announced last week it will accelerate its engine inspection program following the midair explosion of an engine on a Southwest Boeing 737.

The airline said inspections are being performed “out of an abundance of caution” and are expected to be completed in the next 30 days. The accelerated checks are ultrasonic inspections of fan blades of the CFM56 engines, which are manufactured in a joint venture of General Electric Co. and France's Safran Aircraft Engines.

Southwest said it has minimized flight disruptions with aircraft routing to cover open trips, performing inspections overnight and using spare aircraft when available.

The cancellations are not the result of an emergency airworthiness directive Friday by the Federal Aviation Administration, the airline said. It canceled the flights as part of its accelerated engine fan blade inspection program announced Tuesday night after the accident.

The airline advises customers to check southwest.com for the status of their flights.

The engine lost one of its fan blades Tuesday shortly after takeoff from New York to Dallas. Shrapnel punctured the fuselage and one of the plane's windows blew out.

The passenger, a mother of two and bank executive from Albuquerque, N.M., was partly sucked out through the opening and died. The pilot made an emergency landing in Philadelphia.
